Abstract
Provided is a watch case (10) that includes a middle (11) to which are attached a crystal (12) and a back (13) delimiting an internal volume in which is arranged a horological movement (14) intended to drive indicating members. The case (10) also includes a mechanism for actuating an indicator (16) capable of moving in rotation and housed inside the internal volume of the case (10), the actuation mechanism including a bezel (15) capable of moving in rotation and intended to be handled by a user, and a transmission pinion (17) arranged such that it meshes with the bezel (15) and the indicator (16), the respective axes of rotation of the bezel (15), the transmission pinion (17) and the indicator (16) being parallel to one another.
Claims19
A watch comprising a case (10) and a middle (11) to which are attached a crystal (12) and a back (13) delimiting an internal volume in which is arranged a horological movement (14) intended to drive displays displaying a time value, said case (10) further comprising a mechanism for actuating an indicator (16) capable of moving in rotation and housed inside the internal volume of the case (10), wherein said actuation mechanism includes a bezel (15) capable of moving in rotation and intended to be handled by a user, and a transmission pinion (17) arranged such that it meshes with the bezel (15) and the indicator (16), the respective axes of rotation of the bezel (15), the transmission pinion (17) and the indicator (16) being parallel to one another, and
- wherein the transmission pinion (17) comprises an upper toothing (170) and a lower toothing (171), extending coaxially to one another such that the upper toothing (170) meshes with a toothing of the bezel (15) and such that the lower toothing (171) meshes with a toothing of the indicator (16).
A watch comprising a case (10) and a middle (11) to which are attached a crystal (12) and a back (13) delimiting an internal volume in which is arranged a horological movement (14) intended to drive displays displaying a time value, said case (10) further comprising a mechanism for actuating an indicator (16) capable of moving in rotation and housed inside the internal volume of the case (10), wherein said actuation mechanism includes a bezel (15) capable of moving in rotation and intended to be handled by a user, and a transmission pinion (17) arranged such that it meshes with the bezel (15) and the indicator (16), the respective axes of rotation of the bezel (15), the transmission pinion (17) and the indicator (16) being parallel to one another, and
- wherein the transmission pinion (17) is engaged in a housing (111) formed in the middle (11), said housing (111) opening out at a lower end and at an upper end into radial openings.
